If it is electrical, why is there attraction between atoms? Shouldn't they repel each other due to outer electrons?

I'm really sorry... I meant Method 1. Thank you very much for your time. I really appreciate it! :smile:

So, is Method 2 correct for the determination of ΔT?

I don't know. Can I? :confused:

Viscous force is directly proportional to velocity. Viscous force only arises when there is movement of the oil drop (eg. when the electric field is removed and the drop falls. Here viscous force will continue to increase until upthrust + viscous force = weight. Then, resultant force being zero...

Thank you very much for your reply! :smile: I am aware that the w represents the work done on the gas and since the gas is expanding (ie. doing work against the atmosphere), w = -pΔV. So Δu = -pΔV + q and since the change is adiabatic, q = 0. Thus, Δu = -pΔV = -30J. I'm having problem with...

Please Help! Thermodynamics, the ideal gas equation and temperature change Hi all! :smile: I'm new here! I hope my question gets answered because I'm really confused. Homework Statement An amount of 0.18 mol of an ideal gas is held in an insulated cylinder fitted with a piston...
